e-Laboratory on Machine Learning in Medicine

Challenges
The challenge of this e-laboratory is to provide a platform to register, process, analyse and model clinical signal and images in a standardized repository complying technical requirements to improve the development of Complex System technologies. In particular to build up an adequate training set for the definition of Tailored to the Problem (TPS) Mathematical Transforms, in the fields of Engineering applied to Medicine and to Life and Cognition Sciences.

During a first phase Artificial Neural Networks (ANN), which are Complex adaptive systems with inference learning emergent properties, are to be used. Later on, other more advanced methodologies are to be tested.

Trained ANN have computational properties enabling them to be considered Universal Approximators as mapping networks. As stated (Hornik, K., 1989) “any lack of success in applications must arise from inadequate learning, insufficient numbers of hidden units or the lack of a deterministic relationship between input and target”. Therefore this e-lab point towards getting adequate learning and managing possible non- deterministic relations between input and target.

Recently, ANN has been used to define new Mathematical Transforms; Tailored to the Problem Specificity (TPS) (Glaría, A., Taramasco, C., Demongeot, J., 2010) and Dynalet Transforms (DT) (Demongeot, J., Glade N., Forest L., 2007).

TPS methodology can be envisioned as part of the development of new Complex System based technologies which has been used in the field of Engineering applied to Medicine and to Life and Cognitive Sciences (IMVC).

Inadequate learning due to the lack of deterministic relationship between data and its classification makes the accuracy of this method to be critically sensitive, on one part, to the representativeness and completeness of data in the input vectors of the ANN learning set and, on the other hand, to the existence of data clusters associated with different classifications in the target vectors.

Collaborative efforts between new transform developers -both, from the Academy and from the Industry- are required to have access to more representative, complete and well documented data. We believe that UNITWIN UNESCO “Complex System Digital Campus”, aimed to potentiate collaborative networks, could be an adequate environment to enrich completeness in ANN Learning Set data.

The main goal of the proposed e-lab is to register, process, analyse and model clinical data, either signals or images, and its classification on systems for which TPS or Dynalet transforms are being developed. A reliable repository, duly completed and properly provisioned with representative data, is a necessity for the development of reliable Mathematical Transforms -such as TPS or Dynalet- in the context of complex systems technologies with inference learning emergent properties in IMVC domain.
